Chemical Structure
Description
Ethyl (Z)-2-fluorobut-2-enoate (CAS 58089-70-6), molecular formula C6H9FO2 and molecular weight 132.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl (Z)-2-fluorobut-2-enoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
